Hi All,
Cutting a long story short, I’ve been having problems with my prints since I bought my Anycubic Chiron that I’m having a tough time getting to the bottom of.
Putting it simply, I’m find in the bottom layers of my print are being compressed/over extruded to the point where there is noticeable bulging on the sides of my prints (again, only for the bottom layers though). It doesn’t matter if I tell Cura to print either 10 or 5 bottom layers (@ a 1.2 layer height), after about the 4th layer, the filament starts to become ‘wavy’ which I can put down to either over extrusion or some type of z axis compression. It’s worth noting that the rest of the print comes out perfectly.
This wouldn’t normally bother me but for some recent prints, I need fairly rigorous dimensional accuracy as what I’m printing is going to be functional (basically a matrix of 10, 13mm x 13mm square holes to fit 12.5mm square buttons).
I’ve tried various things; lowering print temps from my normal 205c (for 40m/s prints) to 195c, extruded calibration (was fine) and generally playing with the infill settings but I can’t seen to solve it.
Any ideas? Let me know if you need any more info wrt my settings, this is my first post! :)
Thanks
